t has been stated that cars cause the most pollution on short journeys. Evaluate this statement in terms of the rate and equilibrium position of the reaction shown in equation 31.1. (equation 31.1 is in the picture) Pls help me with this question.

Which would likely increase the rate of a chemical reaction? A. Cooling the reaction mixture. B. Decreasing the concentration of the reactants. C. Decreasing the surface area of the reactants. D. Adding a catalyst to the reaction mixture.

Reaction rate increased by an increase of surface area of a reactant. One way to increase surface area is to add catalyst crush solid reactant into smaller pieces increase reactant's temperature increase reactant's concentration

Which reaction would happen faster: the oxidation of a steel plate or the oxidation of a ball of steel wool? Explain your answer using collision theory.

Because there is stability in reactants, A) before two reactants can form products, they must overcome an activation energy B) they can form products if one reactant loses some activation energy C) they can never form products, unless there in a huge input of energy D) they can never form products

Solve correctly please.

What statement about the catalyst is correct? it increases a value of the equilibrium constant It increases the number of collisions between reacting molecules. It makes the reaction more endothermic. It provides an alternative reaction mechanism with a lower activation energy. It shifts an equilibrium to the right
